This is a repalcer for all the "Runner" enemies in-game.

The Plainrunner is now a blue/purple Chocobo.

The Desertrunner is now a classic yellow Chocobo.

The Leafrunner is also a yellow Chocobo, but with a saddle and bag added. (Chocobo Dungeon style)

And the Snowrunner is a very bland white Chodobo.

I might update this with more detail, but for the time being, here you go!
